Abstract: Embodiments of the present invention provide an antenna and a communications device. The antenna of the present invention includes a plurality of antenna units. Each antenna unit includes a plurality of antenna branches and one feed branch. Different antenna branches in a same antenna unit correspond to different frequency bands. At least one antenna unit pair exists in the plurality of antenna units. A distance between two antenna units in each antenna unit pair is less than a first preset distance. Radiation directions of antenna branches in each antenna unit pair that correspond to a same frequency band are different. By means of the present invention, isolation between the antenna units in the antenna can be increased.

Abstract: An antenna subarray, an antenna array, and a polarization reconfiguration method and apparatus are provided. The antenna subarray includes m antenna elements. m is an integer greater than or equal to 2. The m antenna elements are placed at an interval of 360/m degrees in sequence. A distance between any two adjacent antenna elements is less than 0.5 times an operating wavelength. The distance between any two antenna elements is controlled within 0.5λ, so that polarization reconfiguration may be implemented.

Abstract: This application describes examples of antenna modules, MIMO antennas, and terminals. One example antenna module includes a clearance area, a support, and at least two branches. Each branch is disposed on the support, and a partial projection of the support on a horizontal plane falls within the clearance area, while a projection on the horizontal plane of one end that is of each branch and that is configured to connect to a feed point is outside the clearance area. A projection of a tail end on the horizontal plane is inside the clearance area.
